Previous I started a thread on which to get, so with posters advice I got the MBA. But not the TBD. I decided to keep my imac 27 2.93 with SSD and 12GB Ram since icloud is out. I own and operate my own business and now I need a new setup. I hired a new employee.Now I need to buy a new mac for their office. Usually I always get them a mac. And my wife now takes my MBA to work more than me now. She is a Accountant and loves it. I let her use it since she complains she can't carry the other one. Being the gentleman husband that I am I gave it to her. Owing the MBA it's has not failed my yet. I do a million things at once. The MBA keeps with me at all times. Suprisingly. The Ram is usually used up to about 2GB at all times sometimes 3GB. I do worry about the power needs if I would ever need more. A MBP would fill this need, more powerful core i7 and more Ram up to 16Gb. Weight? Now I have three options: Option 1:Keep imac with 2.93 27 SSD. And buy a new Air with 128 SSD and 13inch. Buy imac for 1700 for new employee. Option 2:Give my imac 2.93 to the new employee so I don't have to spend 1700 on a new one for her. Buy new TBD and loaded Mac book Air. Can get the TBD for $950 and Air for 1600. Option 3: Get TBD and 13 Mac Book Pro with SSD and Core i7 for $1600 same price of the maxed out Air. Add 8GB for $80. Give imac to employee. I need portability and do need some power. Which setup is best. Neg difference between weight of the Air and MP?
